Application filed April 19, 1918.

To all whom it may concern:

Be it known that I, HOMER H. ELLIOTT, a citizen of the United States, residing at Rose, in the county of Woodson and State of Kansas, have invented certain new and useful Improvements in Lamps, of which the following is a specification.

This invention is a lamp attachment and has for its principal object the production of a simple and efficient means for determining the quantity of oil within the lamp.

Another object of this invention is the production of a lamp attachment which consists of atransparent tube connected to the bowl of the lamp, thus permitting the oil level within the bowl of the lamp to be easily determined.

Another object of this invention is the production of a lamp attachment which consists of a transparent tube having inwardly extending ends, the ends being carried by necks extending from the bowl of the lamp, thus holding the tube against displacement and permitting the oil level within the bowl to be determined.

Another object of this invention is the production of a lamp attachment wherein the tube is curved to conform to the contour of the bowl of the lamp, thus being in a substantially out-of-the-way position and also disclosing a neat appearance, as well as disclosing the quantity of oil within the bowl.

Broadly stated, this invention consists of a transparent tube curved throughout practically its entire length to conform to the -contour of the bowl of the lamp, the ends of the tube extending inwardly, a lamp bowl having outwardly extending hollow necks, said necks engaging the inwardly extending ends of the tube, thus holding the tube against displacement and permitting the oil level to be easily determined.

With these and other objects in view, this invention consists of certain novel combinations, construction, and arrangement of parts as will be hereinafter fully described and claimed.

One practical form of construction and assembly of the present invention will be hereinafter described and is illustrated in the accompanying drawing, in which- Figure l is a side elevation of the attach ment as applied to the bowl of a lamp, portions of the bowl being broken away, and

Fig. 2 is a sectional view taken on the line 2-2 of Fig. 1..

Specification of Letters Patent.

Serial No. 229,605.

In the preferred embodiment of the present invention about to be described, it will be noted that the attachment is used in connection with a bowl 5 being carried by a pedestal 6 and having a burner 7 The present invention is especially adapted for use in connection with non-transparent bowls, such as where the bowls are formed of metal or of a non-trans parent glass, thus preventing ready determination of the amount of oil within the bowl. Consequently, without using the present invention, such lamps are frequently filled until they overflow and under other conditions they are burnt dry, as it is comparatively diflicult to determine the quantity of oil within the bowl. The gage tube 8 is formed of transparent glass and is elongated, as illustrated clearly in Fig. 1. This tube 8 is curved throughout its. entire length, thus permitting the same to be carriedat a point adjacent the outer surface of the bowl 5. The ends 9 of the tube 8 extend inwardly, although easy access may be had to the interior of this tube 8. The lamp bowl 5 is provided with openings 10 in its top and bottom portions, while necks 11 are formed on the bowl 5 and extend outwardly and surround the openings 10.

The inwardly extending ends 9 of the tube 8 project into the openings 10 of the bowl 5, thus communicating with the interior of the bowl. The necks ll of the bowl bear upon the inwardly extending ends 9 and in this way form a liquid tight joint at each end of the tube 8. Since the ends 9 of this tube communicate with the top and bottom. portions of the bowl 5, it is obvious an accurate estimation of the amount of oil within the bowl 5 may be readily determined, since the bowl will be entirely empty of oil when the oil reaches the bottom tube 8, or the bowl will be entirely filled, almost to a point of overflowing when the oil reaches the top of the tube 8.

When the gage tube 8 is being blown and is still hot, the end's thereof are bent into engagement with the necks 11. Before the burner 7 is placed in engagement with the bowl 5, a suitable implement may be inserted into the bowl to engage the bent ends and swing the same for causing the bent ends and necks to form a tight closure. Therefore the tube will be firmly held in engagement with the bowl.

Since the ends 9 extend inwardly, it is of a lamp, said bowl obvious that after the device has been assembled, the tube will be positively held against displacement, without secondary securing means, as the inwardly extending ends will prevent such action. Also, since the tube conforms in contour to the bowl 5,

it will be in an out-of-the-way position and will not present an ill appearance. In fact, if so desired, the bowl could be provided with a groove within which the tube could befitted, thus presenting an even outer surface around the bowl and also constitute a shield for protecting the tube.

From the foregoing description, it is ob vious a very simple and eflicient attachment has been provided for lamp bowls of the ordinary nature, which consist of the transparent tube having inwardly extending ends, communicating with the top and bottom of thebowl, thus disclosing the amount of oil within the bowl, while the engagement of the tube with the bowl is such as will prevent accidental displacement of the tube.

The foregoing description and the drawings have reference to what may be considered the preferred, or approved, form of my invention. It is to be understood that I may make such changes in construction and arrangement and combination of parts, materials, dimensions, et cetera, as may prove expedient and fall within the scope ofthe appended claims.

Having. thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a device of the class described, the combination of a bowl having openings formed in its top and bottom, said bowl having necks extending therefrom and surrounding said openings, a gage tube curved throughout its entire length to conform to the contour of" said bowl, said tube having inwardly extending ends, said ends being said necks holding said tube against acci-- dental displacement independent of secondary securing means.

2. In a device of the class described, the combination of a bowl having openings formed in its top and bottom, said bowlhaving necks extending therefrom .and surrounding said openings, a gage tubeeonlorming in shape to the contour of said bowl having angularly extending ends carried by said necks and communicating withithe interior of said bowl, and said ends and-necks holding said tube against accidental. displacement.

3. In a device of the class described, the combination of a bowl having openings formed in its top and bottom, a gage tube having ends extending at an acute angle thereto, said ends inserted in said openings and communicating with the interior of said bowl, whereby the oil level within the bowl may be disclosed, while the inter-engagement between said ends will hold said tube against displacement.

In testimony whereof I aflixtmy signature in presence of two witnesses.
